The main antenna rod 7 and the sub antenna rod 8 constitute the antenna rod 6.

  The main antenna rod 7 is preferably a single rod made of stainless steel with a knob 7b attached to the tip 7e. Since each of the three sub-antenna rods 8 has the same configuration, only one of them will be described, and the description of the internal structure of the other two will be omitted. Of course, the same instruction symbols have the same configuration and function. Further, a locking hole 7 c that locks the upper end portion 14 b of the coil spring 14 is provided at the lower end portion of the main antenna rod 7.

  The sub-antenna rod 8 is made of the same stainless steel as the main antenna rod 7, and can be pivoted through the connecting pin 15 in three slits 10 a provided at an interval of 120 ° on the upper side of the outer peripheral portion of the slider 10. An attached base 8a, a cylindrical storage cylinder 8b in which the base 8a is inserted and fixed to the lower side, and a slide member 8c attached to the storage cylinder 8b so as to be slidable in the vertical direction; The slide member 8c includes an extendable rod 8d attached in the axial direction. The extendable rod 8d has a knob 8e attached to the tip and is fitted in a groove 8f provided on the outer periphery of the slide member 8c. And a friction member 8g made of a spring member having a semi-cylindrical shape. More specifically, as shown in FIGS. 5 and 6, the base 8 a that constitutes the sub antenna rod 8 is provided with an engaging piece 8 h that engages with a leaf spring 16 described later.

  A leaf spring accommodating portion 10b is provided on the outer peripheral portion of the slider 10 following the slit 10a, and the plate is interposed via fixing pieces 16a fitted in mounting grooves 10c and 10c provided on both sides of the leaf spring accommodating portion 10b. The lower side of the spring 16 is fixed, and the free end side of the leaf spring 16 is engaged with the engaging piece 8h provided with the base 8a, and the sub-antenna rod 8 is urged to turn outward. ing. The mounting recess 12c provided at the upper end of the outer peripheral portion of the case body 12 has a substantially U-shaped cross section corresponding to each sub antenna rod 8 and abutting when the sub antenna rod 8 turns and opens. The presented terminals 17 are attached at intervals of 120 ° with the engaging projections 12d fitted into the fixing holes 17a. The number of sub-antenna rods 8 is three in the embodiment, but the number is not limited. Three or more may be sufficient and three or less may be sufficient.

  Further, the configuration of the sub-antenna rod 8 may be freely extendable as shown in the drawings, but is not limited to this. You may comprise like the main antenna rod 7. FIG. Further, the main antenna rod 7 may be configured to extend and contract like the sub antenna rod 8.

  The locking release means 11 has a locking portion 19 a that is rotatably attached via a connecting pin 18 to a front substantially rectangular mounting hole 12 b provided on the upper end side of the outer peripheral portion of the case body 12. A lever 19, a push button member 9 attached to the side of the second housing 3 to press the side beyond the fulcrum of the locking lever 19, and the locking lever 19 are urged to rotate in one direction. For this purpose, it is composed of elastic means 20 provided between the case body 12 and the locking lever 19.

  Accordingly, as shown in FIGS. 2 and 3B, each sub antenna rod 8 constituting the antenna rod 6 is folded and attached to the main antenna rod 7 when the antenna device 5 is not used. In the state, it is housed in the case body 12 together with the main antenna rod 7. At this time, as shown in the drawing, the slider 10 is in a state of being pulled into the case body 12, and the coil spring 14 is contracted to pull the slider 10 downward to be housed in the case body 12 together with the slider 10. is there. Further, in this state, the knob 8e of each sub-antenna rod 8 is accommodated in a recess 7d provided on the outer periphery of the knob 7b of the main antenna rod 7, as shown in FIG.

  When the antenna device 5 is used, when the knob 7b of the main antenna rod 7 protruding from the upper end portion of the case body 12 is grasped with a finger together with the knob 8e of the sub antenna rod 8 and pulled upward, the slider 10 becomes a coil spring. 14, slides upward in the case body 12 against the tensile force of 14, and the main antenna rod 7 and the sub-antenna rod 8 are pulled out of the case body 12, and thus the second housing 3. When the engaging recess 10d provided in the slider 10 is locked by the locking portion 19a of the locking lever 19 and pulled out until the slider 10 stops and is released, it is pressed by the knob 7b of the main antenna rod 7 with fingers. Each of the sub-antenna rods 8 is automatically opened by the elasticity of the leaf spring 16 acting on the base portion 8a, and is shown in FIGS. Since the open manner, it is possible to use the antenna rod 6. Then, after the sub-antenna rod 8 is opened, the telescopic rod 8d can be pulled out from the storage cylinder 8b and stored to adjust the radio wave sensitivity. When the telescopic rod 8d is pulled out or pushed in from the storage cylinder 8b, the expansion rod 8d is stably stopped at an arbitrary position with respect to the storage cylinder 8b by the friction member 8g. .
